Linux column命令详解

column命令用于格式化列信息。

column命令的使用格式如下：

column [-tx] [-c columns] [-s sep] [file ...]

常用的选项

-c      Output is formatted for a display columns wide.

-s      Specify a set of characters to be used to delimit columns for the -t option.

-t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by
        default, or with the characters supplied using the -s option.  Useful for pretty-printing displays.

-x      Fill columns before filling rows.

eg:

#mount | column -t |sort
